MOD 15/16

3. A network administrator uses the command ip route 172.18.0.0 255.255.0.0 S0/0/1 to configure a floating static route on a router. That route will function as a backup route to reach the EIGRP learned network 172.18.0.0/16. After this configuration, the EIGRP route is removed from the routing table even though EIGRP is still functioning properly. Why is the static route not functioning as intended?

The administrative distance value is not high enough on the static route.

24. Refer to the exhibit. An administrator is attempting to install an IPv6 static route on router R1 to reach the network attached to router R2. After the static route command is entered, connectivity to the network is still failing. What error has been made in the static route configuration?

29. Refer to the exhibit. The Branch Router has an OSPF neighbor relationship with the HQ router over the 198.51.0.4/30 network. The 198.51.0.8/30 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/1/1 100 was issued on Branch and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up?

Change the administrative distance to 120.

12. What command, or set of commands, would be used to determine if the following configuration on router HQ works as designed?

HQ(config)# interface serial 0/1/0 HQ(config-if)# shutdown HQ(config-if)# end HQ# show ip route

10. What is the purpose of a floating static route?

It allows an alternate connection to be used when the preferred link fails.

5. Which statement describes the sequence of processes executed by a router when it receives a packet from a host to be delivered to a host on another network?

It de-encapsulates the packet, selects the appropriate path, and encapsulates the packet to forward it toward the destination host.

10. What does the letter C mean next to an entry in the output of the show ip route command?

It identifies a network that is directly connected to the router.

9. What is a characteristic of a default static route? ​

It identifies the gateway IP address to which the router sends all IP packets for which it does not have a learned or static route.

22. Refer to the exhibit. Which set of commands will configure static routes that will allow the Park and the Alta routers to a) forward packets to each LAN and b) direct all other traffic to the Internet?

Park(config)# ip route 0.0.0.0 0.0.0.0 192.168.14.1Alta(config)# ip route 10.0.234.0 255.255.255.0 192.168.14.2Alta(config)# ip route 0.0.0.0 0.0.0.0 s0/0/0

23. Refer to the exhibit. The small company shown uses static routing. Users on the R2 LAN have reported a problem with connectivity. What is the issue?
